This line comes from Monty Python and the Holy Grail, the 1975 comedy film by the Monty Python troupe. It appears in the 'bring out your dead' sequence, in which a plague cart collector tries to take away a man who protests that he is not dead yet and then cheerfully insists that he feels happy. The moment has long been quoted by fans of British comedy, and the short audio clip now circulates on soundboards and in short videos as a compact reaction. Its lasting appeal is the cheerful refusal to accept a hopeless situation.
